Hammer cushions are furnished mainly to safeguard influence hammers from harmful forces all through Procedure and to allow the maximum level of useable Electricity to generally be transmitted towards the pile although blocking harming energy from becoming rebounded for the hammer. With just a few exceptions, Just about all effects hammers air/steam, diesel and/or hydraulic hammers require the use of cushion. Producers, inside the design of their hammers, make engineering decisions concerning the total and sort of cushion expected for the different types within their item line. Certain varieties and sizes Foundation reinforcement with micro piles of cushioning, once identified, are furnished for in attachments to the base in the hammer, straight under The purpose of effect and usually in conjunction with the travel cap design and attachment.
